Biomechanical in-vitro analysis of the soinal column loading with transpedicular fixation

Abstract

The aim of the biomechanical study was laboratory "in-vitro" testing and measurement of spinal column axial loading. The biomechanical simulation tested the thoracolumbar spinal cadaver with anterior column defect instrumented by the transpedicular fixation.
